My Black & Decker Cordless Drill's Charger has packed up, the Transformer has burnt out. On the casing it says that it is 17.4V DC, 200mA, 3.5VA. What I need to know is, would I have to replace this Transformer with a 17.4V Transformer or what rating Transformer should I use?

Product Detail Model No.: HB-1206S The item is used for charging 6V-12V lead-acid batteries Max Charging Current: 6A AC Power Input: 64W Output: 6/12V DC 3. 52A Batteries Capacities: 15AHR-80AHR Unit Packing: Colorful box Dimension: 18cm x 10cm x 20cm G. W. / N. W.: 1. 85KG/1. 75KG Certifications: GS, CE, BS, ROHS, SAA
Main functions: (1) The HB-1206S battery charger has the features of convenient operations, reliable safety and high performance. (2) During charging, if turn up overload, the battery charger will keep itself at normal current and normal voltage with its self-automatic protecting function. (3) If being short circuit, the battery charger will switch off itself, and turn normal after one or two minutes. (4) The output current of the battery charger is very stationary, so it can protect the battery charger very well. It only costs 3 or 4 hours to fully charge the batteries. (5) Indication of charging: the battery charger has 6 pilot lamps. The more pilot lamps shining, the less electric quantity is. The charging process finishes when all the pilot lamps go out. (6) The battery charger can be switched between 6V and 12V, so it can charge for 6V and 12V accumulators. You can select 6V or 12V according to your own needs. (7)The operations are very convenient: Put the red clip to the positive pole of the accumulator which indicated "+", and put the black clip to the negative pole of the accumulator which indicated "-", then plug in power source, the accumulator will be charged.
Ouch, it is highly likely that you have overpowered the gps and it will need some internal repairs. If the item is less than 1 year old Garmin may fix it for you at no charge. If it is over 1 year old you can call them at 1-800-800-1020 .. It would probably be a good idea not to tell them that you may have caused the problem. We would not want you to void your warranty. Sorry for the bad news and please dont forget to rate me. Have a nice night.
My condolences. I would suggest you plug the unit in to your computer's USB port using an appropriate data cable (in case you no longer have the Garmin data cable, there are lots of devices, including cameras, that use such a cable with the large USB plug at one end and the mini-USB at the other). That would give you a handle on where the fault lies -- in the auto charger cable itself vs the nuvi's socket. If the nuvi charges from your computer, you're halfway home; if not, I suspect the cost of repairing the nuvi's USB jack could exceed the cost of a replacement unit.
The power supply or voltage transformer or possibly capacitor is burnt out. You will have to visually inspect the main control board for burn marks and swelled up capacitors. You can use an ohmmeter to test them as well.
Internally , the Rider is very similar to other tomtom models . From what you describe it sounds like your charger has gone faulty ( quite common ) . There is a sensing wire that goes from the charger to the plug tip to check the voltage is at 5v . If this sense wire becomes detached or broken then the charger will increase the voltage and unfortunalely , in turn fries 2 chips inside your TomTom . ( these are numbers U24 and U25 in most tomtoms ) . Its not possible for a standard electronics technician to repair these as it need someone experienced with these tiny components and also requires use of special tools and soldering techniques. You will have to have it repaired by either TomTom or a suitable TomTom repair centre . Even then , if the blown chips have got really hot then it's possible they have burnt the circuit board tracks and in this case a repair isn't possible. Throw the existing charger away as if you do get it repaired plugging that one in could easily cause your TomTom to blow again. You can check the voltage output of your charger using a multimeter which would probably confirm what I say above . Sorry to be barer of bad news.... Good Luck
Sounds like either a bad charger or a bad rechargeable battery pack inside of the GPS. If the unit doesn't remain powered up even when it is plugged into the charger, my guess is that the charger is the problem. Do you have an alternate way to charge the GPS? Like a 12 volt vehicle power cord or a USB cable to connect it to your computer? If so, try charging the GPS using that alternate method. If the item charges and functions normally, you will know for sure that the problem lies with the charger. If not, then the problem is either the battery pack inside the GPS or some other part of the unit's charging circuitry. In that case, you should contact Garmin technical support for additional assistance.
